Edit: Please always enclose logs and debug info with ```, otherwise they’re really unreadable. I have done that work for you now.
Did you try “Login with email”, as described on https://davdroid.bitfire.at/configuration/webde/?
Hello rfc2822,
yes, I tried that before. If I use this option, the Carddav option is not made available (CalDAV is working fine, however). The address book sync. interval is set to “-”.
@mrlpr Then I don’t have any ideas because it works here. Logs say:
2016-06-01 14:46:05 8 [HttpClient$1] <-- 401 Unauthorized https://carddav.web.de/CardDavProxy/carddav/.well-known/carddav (1768ms)
Maybe there’s some special setting like two-way auth activated for your CardDAV?
